Duplicate Words Checker

You are given one or more paragraphs. For each paragraph, determine if it contains any duplicate words. Words are sequences of alphanumeric characters and are compared in a case-insensitive manner. Punctuation is ignored. If any word appears more than once in a paragraph, output (DUPLICATES); otherwise, output (UNIQUE).
